Letters Patent No. 108,651, dated October 25, 1870.

IMPR'OVEME'NT IN CARPET-CLEANERS.

The Schedule referred to in these Letters Patent. and making part of the same To all whom 'it may concern: y

Beit known that we, ROBERT Tenn-r and Funnnn'ICK W. HAFIIEMEYER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carpet-Cleaners; and we -do hereby declare the following to be a full, clear, and. exact description thereof, reference being had to 'the accompanying drawing making a part ot' this specification, iu which- Figure 1 is a side elevation of our invention, and

Figure 2, a vertical trausvcrse'section on line (l d.

Similar letters of reference, where they occui in the separate figures, denote like parts.

Our' invention relates to that class of carpet-cleaners wherein th carpet is operated upon by a system of rotating beaters; and l The nature of' our improvement consists- First., in attaching the beaters to the wings ot' arotating fan, whereby thev'current of air produced by same is loosened by the beaters.

Second, in passing thc'carpet around a system of cylinders and over an apron so arranged as to be capable of being adjusted to any proper oblique angle to bring the carpet in contact with the beaters; and

llhird, in the manner of' adjusting the cylinders, whereby the proper tension of the carpet is obtained.

.To enable others skilled in the art to construct and use our invention, we will proceed to describe the same with reference to the drawing.

A A2 represents the frame, which may be as shown, or may be of any suitable form Ot construction that will receive the working parts ofthe machine.

B B2 represents the cylinders that receive the carpet, which revolve upon bearings secured in boxes 1 2 3 4, attached to the sides of the posts of the frame by means of bolts f f f f passing through slots or moriices Ii i 'it' out therein, thus admitting of said cylinders being raised or lowered and firmly held at any given point.

B represents a third Cylinder, which revolves upon I bearings resting within the posts of the frame;

Attached to, and suspended from, said bearings apron 1D, so arranged as to admit ofb an oscillating movement, and is held at any proper adjusted angle the fan may remove the dustfrom the carpet as theA by means of stirrups F F2 pivoted to its end and lower edge, and secured tothe inner sides of the posts by boltspassing through slots e e out therein. Said apron may be constructed of wood, covered, on the side coming against the carpet,w`ith wire-cloth of any desired size and texture.

G represents a system of rotating fans that is attached to shaft G2.

Said shaft revolves upon bearings -secured in the upper end of posts A Ai of the frame, and is provided,

at its cud, with pulley H, to which is applied the power for operating the fan; f

The outer edges of lsaid fans`are perforated at graduated distances to receive a series ot' beaters, L. Said beaters may bc constructed of twine or rope ot` any desired size. l

Our machine is operated as follows:

Carpet M is placed around cylinder B", the end carried upward over cylinder B, thence downward over the Oblique surface ot' apron D, and around cylinder B. Boxes l 2 3 4 are then adj usted, giving the propel' tension to the carpet. Fan G and said cylinders are then given a rotating motion, which conveys the carpet from cylinder Bl to and around cylinder B, thus bringing the same in contact with the beaters H of fan G, whereby the dust is loosened and removed by the current fromthe fan. Y

Having thus described the nature'and object of our invention,

What we claim as new, and desire t-o secure by Let- 1. The rotating fau G, when provided with a series of beaters, H, and arranged to operate substantially as and-for the purpose specified.'

2. The adjustable apron D, arranged to operate substantially as and for tho purpose set forth.

3. 'lhc adjustable boxes l 2 3 4, in combination with the cylinders B, B", and B, the whole arranged substantially 'in the manner and for the purpose specified.
